The Lord Chancellor may by regulations provide that a person who is ordered by a criminal courts charge order to pay a charge must pay interest on the charge so far as it remains unpaid.
The regulations may, in particular—
make provision about the rate of interest,
make provision about periods when interest is or is not payable, and
make provision by reference to a measure or document as amended from time to time.
The regulations may not make provision for a rate of interest that is higher than the rate that the Lord Chancellor considers would maintain the value in real terms of amounts that remain unpaid.
An amount of interest payable under the regulations is to be treated as part of the charge ordered to be paid by the criminal courts charge order.
